WordPress 4.9 Release Candidate

RC means we think we’re done, but with millions of users and thousands of plugins and themes, it’s possible we’ve missed something. We hope to ship WordPress 4.9 on Tuesday, November 14, but we need your help to get there. If you haven’t tested 4.9 yet, now is the time!

Developers, please test your plugins and themes against WordPress 4.9 and update your plugin’s Tested up to version in the readme to 4.9. If you find compatibility problems please be sure to post to the support forums so we can figure those out before the final release — we work hard to avoid breaking things. An in-depth field guide to developer-focused changes is coming soon on the core development blog. In the meantime, you can review the developer notes for 4.9.
